    Abstract: Embodiments provide a resource scheduling method, which can support reduction of transmission resource overheads in resource scheduling. The method is applied to a wireless local area network, where a next generation protocol followed by the wireless local area network predefines locations of resource units possibly allocated from a to-be-assigned frequency domain resource. The method includes: generating, by a sending end, resource scheduling information, where the resource scheduling information includes a bit sequence to indicate an actual allocation of a resource unit(s) from the to-be-assigned frequency domain resource, and at least some bits in the bit sequence are to indicate whether one or more of said resource unit locations possibly allocated for the to-be-assigned frequency domain resource is\are the actually allocated resource unit(s).

    Abstract: An association establishment method and apparatus for carrying out the method are described. The association establishment method includes broadcasting, by an access point (AP), a trigger frame, wherein the trigger frame is used to trigger one or more unassociated stations STAs to perform uplink data transmission and indicate one or more available subchannels for random accessing of the unassociated STAs. The method further comprises receiving, by the AP, one or more association request messages sent on available subchannels acquired by the unassociated STAs. Thereafter, the AP broadcasts a multi-block acknowledgement M-BA frame, wherein the M-BA frame includes one or more pieces of association acknowledgement information and the association acknowledgement information is acknowledgement information of the association request message.

    Abstract: The present disclosure relates to methods, apparatus, and systems for a physical layer protocol data unit (PPDU) transmission. One example method includes generating a PPDU including a signal extension (SE) field arranged after a last orthogonal frequency division multiplexing (OFDM) symbol of a plurality of OFDM symbols, the PPDU including indication information in a high efficiency signaling field (HE-SIG), the indication information being generated based on a symbol length of the SE field and configured to indicate whether a receive end needs to adjust a calculated quantity of the plurality of OFDM symbols, and sending the PPDU to the receive end.
